What is the area of a triangle?

The area of a triangle is defined as the total space occupied by the three sides of a triangle in a 2-dimensional plane. The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h.

From the given figure,

Height of a triangle is 8 units and the base of the triangle is 6 units.

Here, area = 1/2 ×6×8

= 24 square units

Therefore, option B is the correct answer.

Answer part A and Part B

Answers

Answer:

first one is 20 and second is 21

Step-by-step explanation:

7/(1/3)

To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:

7 x 3 1

21 1

Thus, the answer to 7 divided by 1/3 in fraction form is:

21 1

To make the answer to 7 divided by 1/3 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:

21 / 1 = 21

The answer is rounded to the nearest two decimal points if necessary.

21/1 is an improper fraction and should be written as 21.

The semicircle below has a diameter of 20. Find the area of the blue region.

Answers

Answer:

Step-by-step explanation:

Use the area of semicircle minus the area of the triangle. Area of the semicircle is 10^2 * pi / 2 = 50 pi, the area of the triangle is 12*16/ 2 = 96. The the area for the blue part is 50 pi - 96 = 61.07963268 or 61.

If it is helpful, plz give me Brainliest.

Answer:

50pi - 96

Step-by-step explanation:

The radius of the semicircle is 10, so the area of the entire semicircle is 1.2*10^2 pi = 50pi

The white triangle has an area of 1/2*12*16 = 96 so subtracting it shows that the blue area is 50pi-96

The square prism has a base length of 2 ft. Which describes the cross-section of the prism that is perpendicular to the base?

a rectangle with two 12-ft sides and two 2-ft sides

a rectangle with two 12-ft sides and two sides that are shorter than 2 ft

a non-rectangular parallelogram with two 12-ft sides and two 2-ft sides

a non-rectangular parallelogram with two 12-ft sides and two sides that are longer than 2 ft

Answers

The option that describes the cross-section of the prism that is perpendicular to the base is A. a rectangle with two 12-ft sides and two 2-ft sides.

How to explain the rectangle

A square prism has a square base. When we cut a prism perpendicular to the base, we get a cross-section that is a rectangle with the same dimensions as the base. In this case, the base of the prism is a square with a side length of 2 ft, so the cross-section will be a rectangle with two 12-ft sides and two 2-ft sides.

The other answer choices are incorrect. A rectangle with two 12-ft sides and two sides that are shorter than 2 ft is not possible. A non-rectangular parallelogram with two 12-ft sides and two 2-ft sides is not a cross-section of a square prism. A non-rectangular parallelogram with two 12-ft sides and two sides that are longer than 2 ft is not a cross-section of a square prism, because the sides of a square prism are all the same length.
